Chemical Structure
Description
The occurrence of 4-Bromo-N-[(2Z)-3-methyl-2,3-dihydro-1,3-thiazol-2-ylidene]benzene-1-sulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-N-[(2Z)-3-methyl-2,3-dihydro-1,3-thiazol-2-ylidene]benzene-1-sulfonamide (CAS 866010-86-8), molecular formula C10H9BrN2O2S2 and molecular weight 333.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-N-[(2Z)-3-methyl-2,3-dihydro-1,3-thiazol-2-ylidene]benzene-1-sulfonamide (C10H9BrN2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 333.22 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
